1. Residential dwellings shall have their quantification of usage based on one of the following:
A. Residential dwellings with no back flow prevention device and/or new construction permitted after January 1, 2020 shall have their quantification of usage based on metered water used during the billing period. If a residential customer has a consumptive use of water, or in some other manner uses water which is not returned to the wastewater collection system, the user charge for that customer may be based on a secondary water meter installed and maintained at the customer's expense and in a manner acceptable to the City.
B. Residential dwellings with a back flow prevention device and/or those desiring "average billing" shall have their quantification of usage based on actual water used during the months of December, January and February with the number of days in each month based on the billing zone. This usage is billed during the months of January, February and March, hereinafter referred to as the "base," with the remaining nine months of the year (April through December) being billed at the average monthly water usage for the most recent annual base period.
In the event the newly established average varies by fifty-one percent from the previously established average, one or more months of the base has zero usage, or the customer is new to the water utility, the base period shall not be used. The monthly user's charge shall be based on the previous year's history or as follows.
(1) A dwelling unit occupied by one person shall have a monthly sewer charge based upon a consumption of 1,600 gallons;
(2) A dwelling unit occupied by two persons shall have a monthly sewer charge based upon a consumption of 3,200 gallons;
(3) A dwelling unit occupied by three persons shall have a monthly sewer charge based upon a consumption of 4,300 gallons;
(4) A dwelling unit occupied by four persons shall have a monthly sewer charge based upon a consumption of 5,400 gallons;
(5) A dwelling unit occupied by more than four persons shall have a monthly sewer charge based upon a consumption of 5,900 gallons.
The sewer use charges set forth above shall be imposed until a "base" period has been established.
C. In the event a residential customer moves from one dwelling to another within the City, the City will determine sewer use charges as established in paragraphs A and B of this section. If the customer desires "average billing" the "base" period which was applicable to the previous residence shall remain in effect until a new "base" period has been established.
D. In the event a residential customer resides or moves to new construction permitted after January 1, 2020 and/or has a secondary water meter, the City will determine sewer use charges as established in paragraph A of this section and "average billing" will not be allowed.
E. A change from actual billing to average billing or from average billing to actual billing may be granted on a one time only per customer basis. This one time bill adjustment will have a maximum period of three months.
2. 2. Industrial, commercial, and multi-unit residential dwellings with more than two units shall have their quantification of usage based on metered water used during the billing period. If a commercial or industrial customer has a consumptive use of water, or in some other manner uses water which is not returned to the wastewater collection system, the user charge for that customer may be based on a secondary water meter installed and maintained at the customer's expense and in a manner acceptable to the City.
